'My present invention relates to improvements in automobile heating systems of the type utilized as an auxiliary device for heating the interior of automobiles. Thepri mary object of the invention is the provision of an inexpensive appliance that may be adapted for use with automobiles of various 7 makes to provide an efiicient and economical heater for the interior of the car. Means are provided whereby the air may be heated from the exhaust manifold, or the air may be heated by passing over hot water pines from the cooling system of the automobile, but in either case the warmed or heated air is forced into the interior ofthe automobile and distributed as desired, Means are provided whereby the warm air may be distributed to interior of the car, or to the windshield for the urposeoi clearing the glass plate of the shield, or the air may be directed for both of these uses.

The invention consists in certain novel combinations and arrangements of parts as will hereinafter be more fully set forth and claimed. a

In the accompanying drawings 1 haye illustratedtwo examples of the physical embodiment of my invention, one using the exhaust manifold and the other using heat from. the water cooling system of the motor, wherein the parts are combined and arranged according to the best modes l have so far devised for the practical application of the principles of my invention.

Figural is a view showing a portion of automobile equipped with the heating appliance of my invention. Figure 2 is a view with parts in section. Figure 3 is an enlarged detailed view showing the means for clamping the flexible hot air tube to the steering post'of the automobile. Figures is a detailed broken view of the hot air tube showing a universal joint there 5 is a view showing the heating onnected v i the water radiator the toniobile. -e 6 is detail view on. an

in order that the general arrangement and V relation oiiparts may readily be unders ood li have shown so much. of autoinobiie as is necessary, including the loot board 1, the

wind-shield 2 and the hood 3 some instances the radiator 4 is utilized, while in other cases the exhaust manifold 5 is em-'' ployed for providing the heat to the air, and the steering post 6 is alsoutilized in the installationtmy heating appliance. v

In carrying out my invention I employ a hot air housing 7 which is preferably of rectangular shape and is fixed in an opcning in the dash board 1 and this housing is provided ith a reticulated front 8 which maybe. a radiator of the honeycomb type adapted to receive water from the water cooling system of the motor.

The housing? has aside extension 9 to form a closed front, and the front part of the housing supports a slide cover 10 which is of concavo convex formation to provide a hot air chamber in front of the reticulated front 8 of the housing. This slide cover may be moved' longitudinally within the guides 11 secured at the upper and lower parts of the front of the housing and the cover has a-handle 12 with which it may be moved to adjusted position. lln Figure *4" the cover 10 is in position whereby the interior of the automobile may be heated and also whereby warm air-currents may be dirested over the wind-shield to melt ice and snow thereon-' i I The slide hover 10 is fashioned with an air tube 13 towhich a pipe 14 is attached,

this pipe His provided with a universal joint as 15. The flexible air tube 16 is connected to the universal joint and thisfieitible tube is fastened at its end with a nozzle l7.' It will be apparent that the nozzle end oi the flexible tube may be passed over an extensive area of the windshield on its illher side for the purpose of warming the glass and thereh' melting any ice or snow on the exterior ace of the wind-shield.

The flexible warm air tube is preferably supported from the steering post 6, and tor this purposel employ a clamping clip 18 which is clamped by a bolt 19 on the flexible air tube, and by the use of an angle plate 20 and an annular clamp 21, the latter on. the steeringpost, a ilezible joint is provided between the flexible air tube and the supporting steering post. llhis flexible joint is provided with spring bolts 22 and 2-3 for the clamp members and angle plate, and bolt springs 24: and nuts 25 are used for retaining flexible joint in adjusted position, Thus it will be apparent that the flexible its air tube 16 11 use of the universal joint 15 and the flexible. joint between-the air tube and the steering post, may be moved through a considerable area for the purpose'of warming the wind-shield for the purpose de-' scribed.

Ii -front of the housing 7 andlocated beneath the hood 3 of the automobile,'a

motor casing 26 is arran ed to form an extension of the housing. 'fhlS caslng encloses an electric motor 27.and its fan 28, and these members are designed to forceair through the reticulated front 8 of'the'housing 7 and either into the interior of the car, into the flexible air pipe, or into both the car and the air pipe. In Figure 2 it will be seen that the air is drawn through an air heating pipe or stove that encloses the exhaust manifold '5, and this stove has a. screened or reticulated closure 30 through whi'ch air is drawn. It will be apparent that the fan when in operation will draw'air currents through the stove 29 and these air currents of hot water from the motor cooling system..,

The hot water passing through the'housing 7- and its reticulated front 8 provides the .asth'ey are forced throng sing air currentsheating medium for the plash 7 -t e housing Having thus fully described my invention what.[ claim as new and desire to secure by Letters Patent is l 1. A heatin appliance for automobiles comprising a front and means for forcing hot air currents through said front, a' slide cover for control} hug the area of the reticulated front, and'an air tube connected to said slide'cover.

2. In a heating appliance for an automo bile, the combination with a housing having a reticulated front, and means for forcing hot'aincurrcnts therethrough', of an-exten-- sion on the front and guides thereon, a slide a'ble cover movable in said guides to control the area of the reticulated front, a flexible air'tube connected to said cover, and an air nozzle on said tube, whereby'the interior of an automobile may be heated or hot air currents may be distributed from the nozzle.

3. The combination with a stove member adapted to enclose an exhaust-manifold, of a motor casing connected therewith,cand a fan in said casing, a housing connected with the casing having an open front, a slide cover for controlling the area of the open I front, and a flexible air-distributing tube connected to said slide cover for the purpose described. p

In testimony whereof afiix my signature.
